I’m glad you found one Mike. It looks exactly like mine. They are great mounts. I love my SDF on mine (pic below). I also made a bolt-on mounting plate with a Baader/Vixen rail clamp for use with other telescopes like my FC76.

My Gibraltar  azimuth bearing upgrade came today and I installed it. Here's a photo of the old bearing and bottom plate. The tripod arrives Fed Ex tomorrow.

I am not sure if they are available for the Gibraltar, but for my Panoramic I bought the eyepiece holder and handle upgrades, which I found very practical.

Yes the eyepiece holders are available but with a long TV102 a handle is not necessary. Since I upgraded the azimuth bearing if I go to a Sky tour I can use the newer encoders which are more accurate than the older ones.

I enjoy the pan handle on my Panoramic mount. I don’t believe it was ever an option for the Gibralter. At least it wasn’t when my Gibralter was made, it doesn’t have the holes to attach the handle like my Panoramic does.

I have one of the original Gibraltars  with encoders, eyepiece holders, pan handle etc. All the goodies.

I'm following this thread with interest.  There's a Gibraltar in my future, I'm sure, so I'm soaking up all the information I can.  Mike, you mentioned being able to use the newer Sky Tour encoders since you upgraded the azimuth bearings.  Is there any other reason you did so?  I guessing the standard bearings are adequate for a TV-102 or similar four-inch refractor?

The newer style azimuth bearing has no slop whatsoever where the old style bearing is just a post in a Teflon sleeve. Over time the sleeve wears and loosens up. The newer disc type bearing just works smoother kind of  like a DM mount. Also the old style Gibraltar has larger altitude bearings which also are smoother especially with a TV102. The bearings are not as much an issue with a shorter scope like a TV101,Genesis, Genesis SDF etc.

One thing to remember is that if you go with the new style encoders two holes need to be drilled in the side plates (one on each side) to fit the new azimuth encoder and one in the right upper side plate for the altitude encoder needs to be drilled & tapped. Of course if you purchase a new Gibraltar no holes need to be drilled or tapped.

IMG_4621.JPG Finally received my tripod today so other than some scratches from poor packing over the tray studs my mount is together. Here's a photo of the tripod with the sleeve still in.

Lookin’ good Mike! I got a nice soft tripod case with shoulder strap to keep my Gibralter tripod in. The mount goes in a Pelican case. They make transport a whole lot easier.

I just keep the whole thing folded (minus the tray) together and throw it in the back of the Cherokee. So much easier than assembling my Losmandy GM8! (BTW the GM8 will be up for sale)

My Gibralter has the double locks on each leg and didn't need an upgrade kit. I wonder if they made different versions?

Yes they made different versions, do you have the large altitude bearings?
